county of Cook and State-f Illinois, and- Philadelphia, State of Pennsylvania, respectively, have invented new and useful Improvements in Jogging Mechanism for Printing-Presses, of which the following is v a specification.

This invention relates to printing presses of the rapid rotary type, and particularly to sheet delivering mechanism therefor, and has forits object to provide in connection with the receiving table for the printed sheets a straightening mechanism for alining said sheets in an orderly pile, said mechanism operating to engage each sheet as it is delivered from the take-off, and properly aline it with the pile of delivered sheets on the receiving table.

In the present embodiment of this invention, the sheet straightening mechanism, hereinafter called a jogging mechanism, or simply a jogger comprises a plurality of plates or boards, preferably three, that reciprocate flatwise toward and from three sides of the pile of printed sheets, and engage such edges of .each sheet as delivered that project beyond the sides of the pile and jog or push the sheet into alinement with the pile. A fixed plate or board is secured on the receiving table, against which the fourth side of the pile rests and against which it is built up. The jogging mechanism is adjustable for sheets of all sizes within the capacity of the press, and little time is required to change said mechanism to suit any size sheet desired.

The invention consists in the general combination of parts and inthose features hereinafter described, all of which contribute to produce an efficient jogging mechanisin.

A preferred embodiment of my invention will be particularly described in the followingspecification while the broad scope of my invention will be pointed out in the appended claims.

In the accompanying draw1ngs,

Figure 1 is a plan view of the jogging mechanism in position for use Fig. 2 is a vertical longitudinal sectional view of the same and so much of a printing press as is necessary to show its connection therewith.

. Fig. 3 is a bottom plan view of the sheet receiving table with the jogging mechanism mounted thereon.

Fig. 4 is a cross-sectional view taken in a. plane substantially parallel with the axes of the cylinders.

Fig. 5 is a detail view of a modified form of jogger board. 1

Fig. 6 is an elevation partly broken away showing in detail a stop which constitutes a feature of the invention.

I have preferred to describe the invention as applied to a high speed rotary press.

In the drawings, 10' indicates the frame of a printing press in the top of which is mounted printing mechanism including a form cylinder 11, an impression cylinder 12, and a take-off 13, which in the present instance are arranged in parallel with their axes in a common horizontal plane. The take-off 13 in the present form of the invention comprises a revolving skeleton frame made of a plurality of relatively narrow rings or semi-rings 9 spaced at art, each secured on arms radiatingfrom a ub, the several hubs being longitudinally and angularly adjustable upon a shaft 14. Each semi-ring 9 carr es a gripper finger 15 to take-ofl' orremove from the impression cylinder 12 the sheets after being printed and deliver said sheets to a receiving table 16 T opened by a fixed cam in the usual manner to release the sheets which float down upon the receivirig table one at a timeand there pileup. Iii order that the printed sheets as delivered may be gathered on the receiv- ,ing table in an orderly well. 'alined pile of sheets a straightening or jogging. mechanism such as now to be described is provided for abutting the edges of each sheet as delivered and while floating toward the pic,

and for moving the edges of said sheets.

into accurate alinement with the sides of the ile of sheets.

T is mechanism includes joggers which move inwardly andoutwardly while maintainin themselves parallel with the axis of the ta 1e so that they operate to aline the sheets in a pile on the table.

Pivotally mounted upon the top of the inclined receiving table 16 near its lower edge is a fixed alining member preferably comprising a bracket or base member 17 which may be moved along the table to suit the various sizes of sheets printed and af-.

fixed in any adjusted position by a thumbscrew 18, passing through a base member 17. This bracket carries a yielding upright stop or plate 17 preferably pivoted to it. A torsion spring 17 normally maintains the stop in an upright position, that is, projecting upwardly from its lower or pivoted end, but permits it to swing outwardly and downwardly to allow for the free removal of the pack or pile of printed sheets from between the jogging boards presently to be described. Pivoted to rock on a pin or stud 29 projecting from the underside of the table substantially in the center thereof, is a three armed lever 20, one arm 21 of which is adjustably connected to an eccentrio rod 22 provided on one end with an eccentric strap 23 surrounding an eccentric 24 on a continuously running shaft 25 that rotates in unison with the shafts of the printing and impression cylinders and the take-off frames The opposite end of the eccentric rod 22 passes through a sleeve 26 provided with horizontal trunnions 27 pivotally mounted in the ends of a yoke 28 from which the stud 29 extends upwardly through an opening in the arm 21. An operating rod 30 has an eye 31 on one end pivotally mounted on the stud 29 and held -the yoke 28 connected to the arm 21. The

arms 33 of the three-armed lever 20 extend in diametrically opposite directions perpendicular to the arm 21. Upon each arm 33 is pivoted an operating rod 30 similar to the rod on the arin 21, said rods 30 each extending to and beyond one edge of the receiving table 16 as shown in Figs. 1 and 3, and are each guided adjacent theedge of the table by an angle plate 34 affixed to the underside of the table andprovided each with an opening through which the respective rods pass and reciprocate longitudinally as the three-armed lever is rocked by the eccentric. A, slot 35 is formed in the table over each rod 30that extends from the edge, of the table nearly to the cen- 30 on each of which'a stem is adjustable longitudinally and fixed after adjustment has been obtained by a thumb-screw 38. Secured to the inner side of each plate 37 is a jogger preferably in the form of a board or plate 39, the inner face of which is beveled or inclined outwardlyat the top as at 39 for a purpose shortly to be described. The jogger boards which are at the side and the stop plate or plates 17 inclose a rectangular space within which the printed. sheets as delivered are piled against the said stop plate 17. -And the upper edges of the joggers'preferably project high enough so as to extend beyond the position of the sheet when it comes off .the take-off, (see Fig. 2.)

Extending across the frame above the upper end of the receiving table 16 and below the take-ofi' frame 13 is a fixed crossbar 40 to which one or more, preferably two, upstanding sheet engaging stop fingers 41, are adjustably secured, their upper ends extending between two of the rings or semirings of the take-ofl 13. These fingers form stops for the printed sheets and disengage them from the take-01f and its gripper fin gers 15. The parts are so timed that the gripper fingers 15 open just as the advanced frame and extending outwardly above the pile of sheets on the table 16 and substantially parallel therewith, contact with the stop fingers 41, thus not only arresting the forward movement of the sheet but actually causing the latter to rebound by such contact so as to assume a position over the pile as more clearly shown in' Fig. 2, while the gripper fingers and frame continue their rotation. The floating sheet being thus disengaged from the take-oif begins to settle on the receiving table or pile of sheets thereon, during which settlement, if out of line with the pile of sheets, the projecting edge or edges will be struck by the rapidly vibrating jogger board or boards and alined with the pile. Owing to the rapid operation of the press and the distance between the takeoff and the table 16, or pile of sheets thereon, there will be several sheets floating above the pile of sheets and gradually descending on the pile. These floating sheets being at different heights above the pile will have their edges at different distances from the inner walls of the jogger boards because of the outward inclination or level of the upper parts of said boards, and therefore the highest sheet will not be subject to the full force of the blow of the board or boards owing to the lost motion between the board and the edge of the sheet. As the sheets descend the force of the blows increase due to the increasing thickness of the boards and lessening of lost motion, but the sheets being nearer alinement from previous blows, this increasing force does not tend to cramp or 136 crush the ed s of the sheets which finally descend unt' past the inclined portions of the boards and are evenly alined directly upon the pile. v

The jogger boards may be made as in Fig. .4 with the-inner face of the board beveled at the top, or as in Fi 5, with the entire upper portion of the oard inclined outwardly. To assist the disengagement of the sheets from the gripper fingers and cause said sheets to .rebound and fall properly on the table 16, an adjustable block 42 is connected to the upper end of each stop finger 41 by a bolt and thumb nut 43, said bolt passing through a slot in the finger to ermit the'block to be raised and lowered. he

- upper surface of the block is inclined downwardly as at 42'toward the receiving table.

20 that the sheet may be discharged quickly therefromand directed toward the-pile of sheets thereon. The feed table 16 while normally'stationary'ma be adjusted as desired to accommodate it or the work to be done and the size of sheets to be printed, and when the position of the table is to be thus changed a bolt 44 that secures the eccentric rod 22 in the sleeve 26 is loosened to permit the rod adjusting itself to the changed conditions. The same adjustment is employed when the positions of the 'ogger boards 39 are to be changed to suit s eets of difierent sizes. This adjustment will be supplemented when necessary by the individual adjustment of the jogger boards on the rods 30 by loosenin the thumb nuts 38, and sliding the board ongitudinally of its operating rod. In Fig. 4, the back jogger is omitted for the sake of clearness. 1

The revolving take-off 13 in the skeleton form shown is particularly well adapted for the purposes of this press. The partial rings 9 are narrow and have only sli ht contact with the sheets, the latter there ore upon contactmg with the fingers 41, are

thrownout straight by the momentum of the rapidly revolving take-off and are stopped and taken from the take-off in the space over the table, and so that they assume a position where they will fall properly on the pile of printed sheets without relative sliding contact between the sheets such as would result in blurring or smearing and there is no tendency for the sheets to hug or lie close to the take-up which would be the case if the surface of the latter-was'smooth and unbroken. By using the take-01f to receive the sheets from the impression cylinder, the sheets are delivered 1 printed side up, and being jogged into alinement while floating in the air before fallin on the pile, the fresh ink is not smeared.

n the operation of the press, the sheets are disengaged fromv the take-ofi frame in. a positioninclined to the horizontal with the depressed edge of the sheet disposed plurality of times with each sheet as it descends. In this way,'the actual alinement of the sheet takes place in the air just over the pile of sheets so that the sheets sink into place one on top of the other without any sliding action tending to produce blur- It is understood that as the sheets are disengaged from the take off, they are given a slight impetus in the direction of the depressed edge of the table so that as they gravitate downwardly they float or volplane toward the stop 17. The side jogger boards 39' project up beyond the position of the sheet as it is delivered from the take off. They extend substantially at right angles to the fixed alining member 17. 7

In the operation of the press the sheets are fed asusual over the impression cylin- 1 der 12 and passing therebetween and the form 0 linder 11 are printed, after which the prlnted sheets are transferred to the rotary take-off frame 13 and carried around in the direction of the arrow, Fig. 2, and when the take-01f frame is in the position shown in said figure the edge of the sheet engaged by the grippers 15 will strike the stop fingers 41 and said gripper fingers opening at the sametime will release the sheet which rebounds slightly and gradually settles down upon thereceiving table 16 or the pile of sheets thereon. The jogger boards at this time are advancing in unison toward the pile of sheets and shouldthe newly printed sheet just dropped therebetween project beyond one or more sides of the pile, said boards will engage the edges of said sheet and move it into alinement with the pile and against the stop plate 17, the

boards being. so adjusted that their inner limit of movement is defined by the sides of the pile of sheets; the boards then withdraw ready to receive the next sheet.

It is understood that the embodiment of the invention described above is onl one of the many embodiments or forms t e invention may take, and I donot wish tobe limited in the practice of my invention nor in my claims to the particular embodiment deseribed.
